example 1

[0028] Take 200g of Carex lanceolus and 200g of wintergreen, put them into a beater and make a pulp to obtain plant pulp, take 100g of plant pulp, add it to 1L of 50% ethanol solution, stir at 300r / min for 10min, and put it into flash In a type extractor, heat to 80°C to extract for 5 minutes, then transfer to a centrifuge, centrifuge at 6000r / min for 15 minutes, collect the extract and precipitate, repeat the extraction of the precipitate twice, combine the extract, and place it in a flash concentration Concentrate in a container to 15% of the volume of the original solution to obtain a plant concentrate. Take 300g of egg shells, wash them twice with deionized water, soak them in 200mL of 5% sodium hydroxide solution for 20min, peel off the inner membrane of the eggs and wash them with deionized water. Wash the egg shells with water until the washing liquid is neutral, put the egg shells into a drying box, dry them at 105°C until they reach a constant weight, then transfer the...

Abstract

The invention relates to a rice cold-resistant agent and a preparation method thereof, and belongs to the technical field of agriculture. According to the rice cold-resistant agent, plant endogenous cold-resistance substances in carex lanceolata boott and pyrola rotundifolia are extracted, and are compounded with allogenic materials to promote rice growth, improve rice disease resistance and stress and allelopathy resistance, improve tillering, height, accumulation of above-ground and underground biomass and improve cold resistance of rice; and the cytomembrane stability can be kept due to mineral ions in mineral liquid, normal functions of cytomembrane can be maintained, related enzyme systems, such as catalase, peroxidase and superoxide dismutase, are improved to reduce the oxidation effect of free radicals for membrane lipid, the cytomembrane functions can be kept, the cell ultrastructure is prevented from being destroyed, cold resistance of plants can be improved, plant cells are stimulated to secrete peroxidase into cell walls and improve the activity of cells, the firmness of cell walls can e reinforced, and cell collapse injury caused by extracellular freezing and dehydration can be prevented.

Description

technical field [0001] The invention relates to a cold-resistant agent for rice and a preparation method thereof, belonging to the field of agricultural technology. Background technique [0002] At present, there is no clear definition of anti-cold agent, and the literal understanding of anti-cold agent is the ability to resist cold. Therefore, anti-cold agents are defined according to their functions. Any agent, drug or plant growth regulator that can stabilize the plant cell membrane structure, induce a series of physiological and biochemical activities under low temperature stress, and improve plant cold resistance, etc., we It can be defined as anti-cold agent, or anti-cold substance. [0003] The growth of rice requires suitable temperature, sufficient light and water, etc., and its growth has certain requirements on the environment. Low temperature is the main environmental factor for the reduction of rice production, and the loss caused by low temperature and cold d...
